Method

1
For the lemon vinegar, add the lemon juice and zest to a measuring jug and add the same amount of white wine vinegar. Pour into a bottle, shake it up and leave in the fridge for at least 1 month to mature
  • 10 lemons, juiced and zested
  • white wine vinegar

Once the vinegar is ready, pass through muslin to remove the zest and pour into a clean bottle
3
Once ready to cook, slice the halibut fillet finely using a very sharp knife. Spread the strips out onto a plate and sprinkle over some lemon vinegar. Leave for approximately 20 minutes - the fish will start to 'cook' in the acid
